和田—若羌铁路"七带一体"综合防沙技术OA

Hetian-Ruoqiang Railway(He-Ruo Railway)is located in the southern edge of Taklimakan Desert,the second largest flowing desert in the world.Violent wind-blown sand activities pose a major threat to the operation safety of 409.19 km of the railway(50%of the total length).Therefore,wind-blown sand control becomes the key to the successful construction and safe operation of the railway.This paper firstly investigated and summarized the present situation of the hazard of wind-blown sand along He-Ruo Railway,and introduced the comprehensive sand prevention technology of"Seven-Belt Structure"which was explored and summarized in the process of railway construction.The proposed comprehensive technology has achieved the goal of avoiding the sand damage on the railway during the construction period.At present,the overall survival rate of the plants has reached more than 85%,and the plant spacing height is about 1.0～1.5 m,which will escort the safe operation of the railway.The relevant work and results can guide the design,construction and management of similar projects,and provide a basis for the national decision-making in project approval.
